SLIDING CAR-DOOR HANGER.

SPECIFICATION forming part of Letters Patent No. 275,852, dated April 17, 1883.

Application filed January 15, 1883.

To all whom it may concern:

Be it known that I, EDWIN Pnnsoo'rr, of Arlington, county of Middlesex, and State of Massachusetts, haveinvented an Improvement in Hangers for Sliding Doors in Cars, 850., of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Heretofore, in that class of sliding doors and gates supported by one long and one short lever connected together to form a sort of parallel motion, it has been customary to employ a guide at-the upper and lower end of the door, or between its bottom and top, to prevent the door from sagging or tipping, or swinging on its support or connection with the said levers. In practice such guides are objectionable, because it often happens that they are thrown out of proper level or position with relation to the post and line of movement of the door by settling of the building or otherwise, and the door thereafter binds in the groove of the guide and fails to work properly and easily. In my study to avoid these usual close-fitting guides, which acted to prevent the door from sagging or from turning about the horizontal connection with its supporting-lever, as stated, Idiscovered that the door might be effectually guided and kept level by combining with levers substantially such as heretofore used two other levers, and by placing the long levers so as to support the door at opposite sides of its center, and it is in such kind of hanger and as will be described that my present invention consists.

Figure 1 represents in elevation a sufficient portion of a car-body to show a door supported in accordance with my invention, the side of the car being shown as brokenaway, but without disturbing the lever-supports; and Fig. 2, a section of the same on the dotted line ac 00, Fig. 1.

The car-body A, of usual construction, has attached to its side I) a suitable plate or piece, 0, to support the pivots 10 12 of the short levers or bars 0 0 attached at their lower ends by pivots or pins to the longer levers d (2, respectively. The lower ends of these levers (Z (No model.)

02' have pins 2 3,0r they might be rolls, which enter guides made between or in preferably suitable metal plates, ff, secured to the side of the car by suitable screws or rivets. The upper ends of the levers d d engage pivots 4 '5 on a suitable plate or bar, 0, attached to the door 13, thus enabling the said levers to support the door at each side of its center and thus do away with guides such as referred to, and enabling the door to have free spaces 9 9 above and below it. The door is prevented from lateral motion by usual plates, h h. The two levers d d are joined near their lower ends by a connecting brace or bar, 0, jointed thereto, the said connecting-bar being of material assistance when applying the hangers to the door, and also taking a part of the strain, of the pins 2 and 3, and in case of breakage of either of the said pins maintaining the parallelism of the levers d d and supporting the door. The levers d d, from their points of connection with the levers c c to their pivots 4: 5, are longer than from the said point of connection to the pins 2 3 in the said levers, and-also longer than the levers c c, in order that the weight of the door may overcome the tendency of the hangers to assume perpendicular position below the pivotal points 10 12 of the levers c c with the car-body, the

door being held in its highest position when half-way open. Preferably the door will be as much wider than the opening to be closed by it as the length of the plate 0. The plates 0 and c are metal plates to firmly hold the pivots 10 and 12 and 4 and 5, and were it not to insure the correct distances apart of the said pivots, the said plates might be made each in two pieces or dispensed with.

I claim- 1. The two pivoted levers c c and the two door-supporting levers d d, pivoted thereon, combined with the guides for the lower ends of the said levers, to operate as and for the purposes described.

2. The two pivoted short levers c c and the two longer door-supporting levers d d, pivoted thereon, and the guides for the lower ends of the said door-supporting levers combined with the two platesc 6, each respectively In testimony whereoflhave signed my name having two pivots for the said short and long to this specification in the presence of two sub- [0 levers, substantially as and for the purpose set forth. scribing witnesses.

3. The two pivoted levers and the two door- 5 supporting levers d d pivoted thereon, com- EDWIN PREbOOTT' bined with the guides for the lower ends of the levers cl cl and with the connecting-bar e, to operate substantially as described.
